A blank where the flue gas reading should be
The install went well. The engineer filled in the Benchmark checklist in the booklet, left it with the customer, and took a photo for the office. When the office looks, the combustion readings are there but the system cleaning section is blank, and the customer's signature is missing. The booklet is now in the customer's kitchen drawer.
Nobody notices until the boiler breaks down and the manufacturer asks to see it.
The same week, an assessor or manufacturer rep asks to see a sample of commissioning records, and the office realises it has photos of only some of them.
Why checklists come back incomplete
Filling in a paper checklist at the end of a long install, often in a cupboard, is exactly when things get missed. The booklet goes to the customer, so the office only sees a photo, if that. Nothing checks the form for completeness while the engineer is still there.
Service records later in the boiler's life have the same problem: they're entered by whoever services it, sometimes another firm, sometimes not at all.
| Checklist section | Commonly missed |
|---|---|
| Combustion readings | Written but illegible |
| System cleaning and inhibitor | Left blank |
| Controls fitted | Ticked without detail |
| Customer signature | Forgotten |
| Service record | Not updated at later visits |
Boiler cupboards do not help. The engineer is kneeling on the floor, the booklet is on a shelf, the pen does not work on the glossy paper, and the customer is waiting to be shown the controls. Filling every section carefully at that point is harder than it sounds.
What an incomplete checklist costs
Manufacturers may look at the Benchmark record when handling a warranty claim, and gaps make that harder. Customers who lose the booklet have no record. Your own quality checks can't happen because the data only exists on paper in someone else's house. What the manufacturer requires is their call; making sure your records are complete is yours.
It also makes your internal quality checks almost impossible. If you want to know whether all your installers are adding inhibitor and recording it, the answer is sitting in customers' kitchen drawers across the county.
The commissioning capture we build
- Digital form: a phone or tablet form follows the checklist sections in order, so engineers fill it in the way they already think about the job.
- Readings: combustion readings can be entered, imported from your analyser where it exports, or read from a photo of its printout.
- Completeness check: before the job can be closed, the form flags any section left blank. The engineer fills it in or records why it doesn't apply.
- Customer sign-off: the customer signs on the screen, and gets a copy by email alongside their paper booklet.
- Office copy: the record is kept against the job and the property, searchable by address, serial or date.
- Service history: at each later service by your team, the service record is added to the same history.
Whether a digital record replaces the paper booklet is a matter for the manufacturer's scheme and your own practice. We produce both where needed.
Complete records without chasing
Checklists are complete when the engineer leaves. The office has a copy of every one. When a manufacturer or customer asks, you can produce the full record. And your supervisor can review commissioning across the team without collecting booklets.
New engineers also learn faster. The form shows every section in order and explains what is missing, so a newly qualified installer produces complete records from the start instead of learning by having booklets sent back.
Recognise these?
- Benchmark checklists are filled in by hand at the end of the day.
- The office only sees a photo of the booklet, if anything.
- Sections are often left blank or illegible.
- Warranty claims have been held up by missing records.
- Service records aren't kept in one place.
